Greasy Fork镜像

error?

admittedly my first time installing a script, so might be missing something, but I'm getting the following error:

Error: $ is not defined
Line: 32

Does anyone know of a fix?

originally i was installing myself and getting that error; when using the Greasy Fork镜像 installation, i'm getting a different one:
Error: document.body.parentElement is undefined

any fixes are appreciated
